/* ---------- "Biz Sizi Arayalım" — the callback request dialog (front page) ----------
 * One first-party round phone launcher fixed bottom-right, stacked above the WhatsApp dock, and one
 * centred dialog holding the request form. On the front page it opens once by itself after 30 s
 * unless the visitor closed it before in this browser; buttons marked data-callback-open (İletişim)
 * and the launcher open it at any time (docs/DECISIONS.md D-2026-09-11-01, D-2026-09-16-03). callback-request.js validates the form and posts JSON to the backend, which
 * stores the request and e-mails it to the business. Colours come from the site tokens in site.css. */
